(as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) for the registrant and we have:  (a)
    
    Designed such disclosure controls and procedures, or caused such disclosure controls and
procedures to be designed under our supervision, to ensure that material information relating to the
registrant, including its consolidated subsidiaries, is made known to us by others within those entities,
particularly during the period in which this report is being prepared;  (b)

    Disclosed in this report any change in the registrants internal control over financial reporting

affect, the registrants internal control over financial reporting; and 5. The registrants other certifying officer and I have disclosed, based on our most recent evaluation of internal
control over financial reporting, to the registrants auditors and the audit committee of registrants board of
directors (or persons performing the equivalent function):  (a)
    
    All significant deficiencies and material weaknesses in the design or operation of internal
control over financial reporting which are reasonably likely to adversely affect the registrants ability
to record, process, summarize and report financial information; and  (b)
    
    Any fraud, whether or not material, that involves management or other employees who have a
significant role in the registrants internal control over financial reporting. Date: August 7, 2009 /s/ Merrill W. Sherman
